The San Francisco 49ers have added depth to their new-look receiving group, signing wideout Marlon Moore to a one-year contract.

The NFC champion Niners made the announcement Tuesday. Last week, San Francisco acquired Anquan Boldin in a trade from the Baltimore Ravens, who beat the 49ers 34-31 in the Super Bowl on Feb. 3 in New Orleans.

The 25-year-old Moore, a Northern California native from Sacramento, played the past three seasons with the Miami Dolphins after joining them as an undrafted free agent in April 2010. He has 12 career catches for 244 yards and two touchdowns in 29 games.

Mario Manningham is working his way back from reconstructive left knee surgery and Randy Moss isn't expected to return after one season, so Boldin and Michael Crabtree will lead the 49ers unit.
